Latent "D"-Scoring Modeling: Estimation of Item and Person Parameters
Dimitrov, Dimiter M.; Atanasov, Dimitar V.
Educational and Psychological Measurement, v81 n2 p388-404 Apr 2021
This study presents a latent (item response theory--like) framework of a recently developed classical approach to test scoring, equating, and item analysis, referred to as "D"-scoring method. Specifically, (a) person and item parameters are estimated under an item response function model on the "D"-scale (from 0 to 1) using marginal maximum-likelihood estimation and (b) analytic expressions are provided for item information function, test information function, and standard error of estimation for "D"-scores obtained under the proposed latent treatment of the "D"-scoring method. The results from a simulation study reveal very good recovery of item and person parameters via the marginal maximum-likelihood estimation method. Discussion and recommendations for practice are provided.
